Specieation forming part of Letters I Patent No. 34,54l, dated February 25, 1862.

To all whom it may concern.

Be it known that I, JOHN WELDY, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Machines for Sawing Wood; and I do hereby declare that the same are described and represented in the following speciication and drawing. J

To enable others skilled in the art to make and use my improvements, I will proceedto describe their construction and operation, referring to the drawing, which is a perspective view of a sawing-machine with my improvements. f

The nature of my invention and improvements consists in a combination and arrangement of devices for feeding,` and guiding the saw, hereinafter described. A

In the accompanying drawing, act are posts connected by the girders a a, bars B B, and

board C, formingva strongframe, which may be made'inthe form shown or in such other form as will answer the purpose. The braces a2 a2 are fastened to two of the posts and two of the girders to stiifen and brace the frame.y

D is a crank fastened to the shaft A,which carries vthe'gear b, thatvdrivesv thepinion c and shaft F,`which carries the ywheel d.

(Shown in the drawing.)

G' isa rock-shaft with jot'unalsturning in the posts amwhi'ch rock-shaft is provided with a perpendicular arm g and a horizontal arm H. These arms are connected by the brace I,

as shown' in the drawing. The links h h vibrate on the arm H, which they connect to off the carriage j' j, whichl bars are provided `with spurs to hold the wood, which is pressed upon, them by the weighted lever k, connected `to the carriage j, as shown in the drawing.

The carriage j j is arranged to traverse on the girders a a between the barM and board C, as shownin the drawing. After the workman has secured thewood on the carriage une der the saw he draws back the latch n and reyleases the arm or lever g and lets the saw down on the wood and turns the. crank D to traverse the saw which saws the wood, and when he has cut off one length he raises the saw by the levr g and moves the carriage j, a

proper distance for another length and lets the saw down again to saw off another out.

If the weightof the saw-links and ar'uiH do not feed the saw fast'enough, a weight may be added, and if they feed it too fast a weight may be arranged to counterbalance the weight of the saw and links.

The bar i is fastened to the bars M and N to guide and steady the links hh, which traverse each side of it, as shown in the drawing.

Tlie saw may be supported by the bent bar O, to hold it straight with the beam.

I contemplate that a pulley or gear may be I fastened tothe shaft A, to operate the inachine by water, steam,'or other power.

I believe I havedescribed and represented my improvements in .machines'for sawingl wood vso as to `enable any person skilled in 'the art to make and use them.. I will now state what I 'desire to secure by Letters Patent.

I claim- 1 the rock-shaft G, arm H, links 7L h, `and sawvbeam J, constructed to operate substantially as described, for the purpose set forth.

2. In combination with the links which support the Vsaw-beam, the guidefbar Iz', subtanially as described, for the purpose set ort JOHN wnLDv. Witnesses: i
